Hi,
I need to calculate an estimate of the reflected electron beam power in the form of back scattered electrons and secondary electron emissions from a tungsten/Graphite target. The Electron source is a 25kV source with operated at a power of around 25kW. The tungsten. graphite blocks are 50mm x 30mm and is 15mm thick. the heat produced from the surface is extracted by a water cooling system which runs through the tungsten block, below the 15mm thick layer of tungsten.
How do i approach such a problem? how do you calculate the total energy absorbed in the target, the amount reflected?
